I'h'is invention relates to new and useful improvementsin mudguns.

fine object of the invention is to provide an improved mud gun for useat the :mud pits of wells being drilled and arranged :to :move invarious-directions so :as to discharge a mudstream under pressure andstir up or agitate the mudin the pit, whereby the ingredients,particularly :the chemicals, are kept in a thoroughly mixed condition. I

Another object of the invention .is :to provide an improved mud gunarranged to be mounted on the bank of the pit and directed over the pond:andlequlpped with liquidmud supply means and mechanical elements forswinging .it in various directions while discharging mud liquid, wherebythe :mud in the :pi'tis agitated and kept thoroughly mixed.

A further object of theii-nvention is :to provide mechanism for-swingingthe gun in-a vertical arc while also swinging in a horizontal :arc', themechanism being so timed as to cause the gun toswin' p and down morefrequently than it is swung horizontally, thus assuring agitation of theentire mass of liquid mud in the pit. Still another object cf theinvention :is to provide a mud .gunmounting which includes an .el--

bow mounted and packed to swing horizontally from an upright supply pipeand connected at its horizontal end with an elongate barrel, mounted andpacked to swing vertically, whereby a stream may be directed over "theentire area f.

' a pond.

A construction designed to carry out the invention will be hereinafterdescribed together with other features of the invention;

The invention will he more readily understood.

from a readingoi the following specification and by reference to theaccompanying drawings wherein an example of the 'invention'is shown,

and wherein: I I Fig. 1 is a perspective oramudigun constructed inaccordance with the -inventiorl.

- member in section.

ln thedrawings, the numeral: 40 designates an upright liquid mud supplypipe which may convey liqu d-mud from any suitable source. An-1e1- bow Hhas its lower vertical end mounted to rotate in the upper end of thepipe, while its upper horizontal l'leg receives the :reduced tubularshank d2 sorta gumbarrel l3. 'F-Theelbow is :mounted to swing in ahorizontal plane; while the barrel is mounted to .swingin a verticalarc.

- Since thermounting at each end of the elbow is duplicated, :adescription of one will suffice for both :and the same referencenumerals will be used. The *top of "the pipe ill is formed with alateral flange I4 (Fig. 5) and-a ring 15 surrounding the end of theelbow M :is welded in the pipe 10 :below the flange. Packing rings 16,snugly surrounding the elbow and engaging the wall of the pipe, aresupported on the ring i5. .A flange packing -gland :ll' inserted in theupper end of the pipe compresses the packing rings. A supporting flangeI8 is welded around the elbow leg between two packing rings 1.9,, thelower of which rests upon the upper and of the gland H. annular cap .20snugly surrounds the elbow leg and rests on the upper ring 19. Verticalbolts 2 I passthroughthecapi 0., the flange of the gland and -the:fiange 44,, receiving nuts '2! engaging said elements 2.0, I! and i 4,whereby the parts are held in position. In this manner 'the elbow H isvertically supported and is .free to be rotated. Except as to size theelements connecting the shank [2 are thesame.

The gun barrel has a reduced nozzle .22 at its forward end, the shank l2being rigidly attached to the barrel nearer its rear end, which latteris closed. An upright, box form, of standard 23 is provided adjacent theupright pipe l D, the details .03? structure :being unimportant. A rigidhorizontal arm 24 extends outwardly from the vertical leg of the elbowII and has its outer end pivoted to one end of a laterally extendinglink 25,. The opposite :end of the link pivotedon an upright pin .25extending from a crank arm 27, which is provided with adjustment holes28 for varying the travel of the link.

The crank arm .21' extends horizontally from the vertical shaft .29 ofahorizontal beveled. gear .30, mounted in a box 3.0 secured to the rearwall of the standard .23.. The gear .30 .is driven by a beveled pinion3| fastened on a crank shaft 32 mounted in brackets .33 on the standard.The elements which have been described swing the barrel l3 laterally. Onthe opposite end of the crank shaft,.a crank arm .34 is mounted. Aswivel35 provided to the outer end of the arm is pivoted to the lower end of alink 36 which is pivoted at its upper end to a swivel .31. The swivel 3?is pivoted in a bracket 38 depending from the un :dersideof the barrel.13 in rear of the shank l2 and whereby, the barrel is swung in avertical are.

From the foregoing it will be seen that since the crank shaft isconstantly revolving the pinion fastened on a jack shaft M mounted inbearing.

boxes 42. A gear 43, slightly larger in diameter than the gear 35, isfastened on the "end of the jack shaft and in turn, is driv'en'bya'pinion .44

fastened on one end of a driven shaft 45 secured in bearing boxes it.tened on the opposite end of the shaft 45 and driven by an endless belt:38 from a smaller 'pulley 49 fastened on a drive shaft 58. The shaft 59is driven by a suitable motor 5! or other means.

It will be observed that since the crank 34 is A large pulley 4"! isfas-' directly revolved by the shaft 32 and the gear 30 3 is rotated. bythe pinion 3!, the barrel 13 will be swung up and down at a more rapidrate of speed than it is moved laterally. These ratios are, of course,subject to change.

It is believed the operation will be obvious from the foregoingdescription without detailed explanation. The mud stream ejected fromthe nozzle 22, being under pressure, will be directed into the pond ofmud in the pit with sufficient force to stir up the pond. Since theejection covers sub-- stantially the entire area of the pond, the wholebody will be suiiiciently agitated to assure thor ough mixing andprevent settling.
